A bit ago, a co-worker gave me a splined bottom bracket tool for fixing up his MTB.
Today, another co-worker gave me another (different) BB Tool because he bought the wrong one. Funny thing, the BB Tool that co-worker #1 gave me was the BB Tool that co-worker #2 needed. Instead of returning the tool, he gave it to me. Sure I built up a SS commuter bike and gave it to him a year ago, but boy, this getting tools from co-workers for free is great.
I’m always willing to lend out my bike tools, and they’ve been getting lent out a lot lately. Just a small thing I can do to get people out on their bikes. It’s really paying off in a big way.
